Which mushrooms are used in traditional Chinese medicine? The best known are lingzhi (reishi), fu ling (Poria), zhu ling (Polyporus), dong chong xia cao (caterpillar fungus) and yin er (snow mushroom), with shiitake and others used mainly as food. Some have been recorded for around two thousand years. But traditional Chinese medicine (TCM) uses them in a very different way from a Western supplement shelf, and the traditional descriptions are not the same thing as clinical evidence. This guide explains which mushrooms TCM uses, how it uses them, and what modern research has and hasn't confirmed.
TCM has used fungi for at least two millennia. Lingzhi appears in the Shennong Bencao Jing, the oldest surviving Chinese materia medica, compiled around the first or second century CE (Lin 2019). Poria has documented use spanning more than 2,500 years and is one of the most frequently used ingredients in classical formulas (Lei 2025). Polyporus is used for fluid retention (Zhao 2013), caterpillar fungus is a prized and costly tonic, and snow mushroom is eaten as a nourishing food. In TCM these are usually combined in formulas chosen for a person's diagnosed pattern, not taken alone for a named disease. Modern research has confirmed some biological activity, mostly in lab and animal studies, with a smaller number of human trials. Quality is a real concern: lead contamination has been documented in caterpillar fungus products (Wu 1996).
How Does Traditional Chinese Medicine Think About Mushrooms?
TCM doesn't classify mushrooms by their chemistry. It describes each ingredient by its "nature" (warming, cooling or neutral), its "flavour" (sweet, bland, bitter and so on) and the organ systems or "channels" it is thought to enter. A practitioner then combines ingredients into a formula that suits a person's overall pattern, such as "spleen deficiency with dampness" or "lung and kidney deficiency".
This matters for two reasons. First, the same mushroom can appear in very different formulas, so "what TCM uses it for" depends on what it's combined with. Second, TCM rarely uses one mushroom on its own for one disease. The modern habit of taking a single-mushroom capsule for a specific complaint is closer to Western herbalism than to classical TCM.
The classical texts sort ingredients into three grades. The upper grade covers substances considered safe for long-term use to nourish life. The middle grade covers those that treat illness but need some care, and the lower grade covers stronger, more toxic substances. Several fungi, lingzhi among them, were placed in the upper grade (Lin 2019).
Lingzhi (Reishi, Ganoderma)
Lingzhi is the most famous mushroom in Chinese culture. The Shennong Bencao Jing describes several kinds of zhi, traditionally distinguished by colour, and later texts added more detail on habitat and use (Lin 2019). It became a symbol of good fortune and long life, appearing in Taoist writing, poetry and art, and was known by names meaning "auspicious herb" or "divine herb".
In TCM terms, lingzhi is considered calming to the spirit and tonifying to qi, and it was used for fatigue, poor sleep, cough and general weakness. Wild lingzhi was rare, which added to its status. Cultivation in the 20th century made it widely available.
Modern research has focused on its beta-glucans and triterpenes. There are human trials on immune markers and some on sleep and fatigue, though most are small. Our article on reishi for immune support covers the human trials, and our reishi dosage guide covers typical amounts.
Fu Ling (Poria, Wolfiporia cocos)
Poria is less famous in the West but far more common in TCM practice. It grows underground on the roots of pine trees and forms a large, pale mass called a sclerotium. A recent review describes more than 2,500 years of documented use (Lei 2025).
In TCM, Poria is considered bland, neutral and gentle. It's used to "drain dampness", which roughly covers fluid retention, poor digestion and loose stools, and to calm the mind. It appears in a large number of classical formulas, often as a supporting ingredient. Lab and animal studies have found diuretic, anti-inflammatory and liver-protective effects, but human trials of Poria on its own are few (Lei 2025). The same review flags quality problems in the trade, including sulphur fumigation and heavy metal contamination.
Zhu Ling (Polyporus umbellatus)
Zhu ling is a related fungus that also forms an underground sclerotium. TCM uses it for oedema, reduced urination, urinary problems, jaundice and diarrhoea (Zhao 2013). It's considered a stronger fluid-draining ingredient than Poria, and the two are often used together. Modern studies have looked at its polysaccharides and steroids, again mostly in the lab.
Dong Chong Xia Cao (Caterpillar Fungus, Ophiocordyceps sinensis)
The name means "winter worm, summer grass". The fungus infects ghost moth caterpillars underground on the Tibetan Plateau and in the Himalayas, then sends a thin stalk up through the soil. It entered the written Chinese materia medica relatively late, around the 18th century, after a long history of use in Tibetan medicine.
TCM considers it a tonic for the lungs and kidneys, used for chronic cough, fatigue and weakness. Its rarity has made it one of the most expensive natural products in the world. That demand has a cost: a study combining harvester interviews with climate data found production falling across the Himalayan region, driven by both warming and overharvesting (Hopping 2018).
Most "cordyceps" sold today is not wild caterpillar fungus at all. It's either Cordyceps militaris, a related species grown on grain or other substrates, or fermented mycelium. Militaris is not a traditional TCM substitute for sinensis, and the two differ chemically. One analysis found the compound cordycepin abundant in cultured militaris but present only at low levels in natural sinensis (Yang 2009). Our comparison of Cordyceps militaris vs sinensis explains the differences.
Yin Er (Snow Mushroom, Tremella fuciformis)
Snow mushroom is a translucent, jelly-like fungus that's mainly a food in China. It's cooked in sweet soups, often with dates, lotus seeds or pears. TCM describes it as "moistening" and associates it with the lungs and with skin, which helped make it a traditional beauty food.
Research has centred on its polysaccharides, which hold water well and have been studied for skin hydration, immune activity and antioxidant effects (Wu 2019). Human evidence is still limited. Our articles on snow mushroom for skin hydration and the snow mushroom dosage guide go further.
Food Mushrooms: Shiitake, Lion's Mane and Others
China's mushroom tradition blurs the line between food and medicine. Shiitake (xiang gu), lion's mane (hou tou gu, "monkey head mushroom"), wood ear and others are eaten for flavour and also valued for health. They appear in dietary therapy, where food is chosen to support a person's constitution, more than in formal prescriptions.
Lion's mane is a good example of a food mushroom that later became a research subject. A review of its use in digestive disease describes a centuries-old history of eating it in China (Gravina 2023). Today it's studied mainly for nerve growth factor and cognition, which is a modern interest, not a traditional one.
What About Chaga and Turkey Tail?
Chaga isn't a major TCM ingredient. Its traditional use comes mainly from Russia, Siberia and northern Europe, where it was brewed as a tea. Turkey tail (yun zhi) does appear in Chinese use, but its modern fame comes from PSK, a prescription extract developed in Japan, and PSP, developed in China, for use alongside cancer treatment. Our reishi vs chaga comparison covers chaga's background.
Does Traditional Use Prove a Mushroom Works?
No. Long use shows that people found a mushroom worth using and that serious harm wasn't obvious at traditional amounts. It doesn't show that a mushroom treats a particular disease, or that it works better than a placebo. Traditional descriptions were also written in a framework (qi, dampness, organ channels) that doesn't map neatly onto modern diagnoses.
Modern research has confirmed that many of these fungi contain biologically active compounds, mainly polysaccharides, triterpenes and nucleosides. Most of the evidence still comes from cells and animals. Human trials exist for reishi, cordyceps, turkey tail extracts and a few others, but they are usually small. The fair summary is that traditional use pointed researchers in interesting directions, and the evidence is still catching up.
What Are the Safety and Quality Concerns?
Contamination. Mushrooms absorb metals from where they grow, and some products have been adulterated. Two patients in Taiwan developed lead poisoning from a cordyceps product that contained as much as 20,000 ppm of lead (Wu 1996). Our article on heavy metals in mushroom supplements explains what to look for.
Mixed formulas. Traditional formulas combine several herbs, and some herbs used in TCM are toxic or interact with medicines. Know every ingredient in what you take.
Interactions. Reishi may reduce platelet activity, and several mushrooms affect blood sugar or immune activity. Tell your doctor if you take blood thinners, diabetes medicines or immunosuppressants.
Identity. High prices invite substitution. Expensive caterpillar fungus is a frequent target for fakes. Buying from a seller who states the species, part used and extraction method, and who can provide a certificate of analysis, lowers the risk.
How Can You Use These Mushrooms Sensibly Today?
If you're interested in the TCM approach itself, see a qualified practitioner who will assess you and prescribe a formula. If you simply want to try a single mushroom such as reishi or cordyceps, treat it as a supplement: choose a clearly labelled product, start at a typical amount, give it several weeks, and check for interactions. Our guide on how to read a mushroom supplement label can help with the first step.
Frequently Asked Questions
What is the most important mushroom in traditional Chinese medicine?
Lingzhi is the most celebrated culturally, but Poria (fu ling) is probably used most often in actual prescriptions, because it appears as a supporting ingredient in many classical formulas.
Is reishi the same as lingzhi?
Yes. Lingzhi is the Chinese name and reishi the Japanese name for Ganoderma mushrooms. Several Ganoderma species are sold under both names.
Is Cordyceps militaris used in traditional Chinese medicine?
The traditional ingredient is wild caterpillar fungus, Ophiocordyceps sinensis. Cordyceps militaris is a related species that's easier to cultivate and is now widely sold as a modern alternative, but it isn't chemically identical.
Are TCM mushrooms safe?
Most are well tolerated at traditional amounts, but contamination, adulteration and drug interactions are real risks. Buy from sellers who disclose testing, and check with your doctor if you take regular medicines.
Do I need a TCM practitioner to take medicinal mushrooms?
Not to take a single mushroom supplement. But if you want treatment in the TCM sense, with a formula matched to your pattern, a qualified practitioner is the only way to get it.
